Abstract

A new Multi-Input Multi-Output (MIMO) antenna using two modified planar inverted-F antennas (PIFA) is presented in this paper. Both modified PIFA antennas are identical with each having two shorting plates instead of one shorting plate and a slot on the top radiation plate for impedance matching to increase the bandwidth of the antennas. Two slots are inserted on the ground plane to further enhance the impedance bandwidth. Isolation between the two modified PIFA antennas is achieved with the use of a strip connecting the feed plates of the two antennas. Both elements of the modified PIFA cover the frequency band from around 1800 MHz to around 2800 MHz which covers LTE/PCS (1900), UMTS/IMT (2000), LTE/AWS (2100), WiBro (2300), WLAN/Bluetooth (2450) and LTE/WiMAX (2500-2700) and can be used as a 3G and 4G antenna for MIMO and diversity applications.
